An electrolytic capacitor includes a capacitor element that includes an anode part and a cathode part, an exterior body that seals the capacitor element, a first external electrode that is electrically connected to the anode part, and a second external electrode that is electrically connected to the cathode part. At least one of an end face of the anode part or an end face of the cathode part is exposed from the exterior body to be electrically connected to a corresponding one of the first external electrode or the second external electrode. The end face exposed from the exterior body is covered with an electroless Ni plating layer, and the electroless Ni plating layer is covered with an electroless Ag plating layer. The electroless Ag plating layer is covered with the corresponding one of the first external electrode or the second external electrode.

Electrolytic capacitor

An electrolytic capacitor includes a capacitor element, an exterior body, a first external electrode, and a second external electrode. The capacitor element includes an anode body that is electrically connected to the first external electrode and has a porous part on a surface thereof, a dielectric layer that is disposed on a surface of at least a part of the porous part, and a solid electrolyte layer that covers at least a part of the dielectric layer, and is electrically connected to the second external electrode. The exterior body has a first principal surface, a second principal surface intersecting the first principal surface, a third principal surface opposite to the first principal surface, and a fourth principal surface opposite to the second principal surface. The first external electrode and the second external electrode are disposed along the first principal surface of the exterior body to be separated from each other.
